Driven by a personal loss of his grandmother to oral cancer, Dr. Ranjan devoted his career to raising awareness on oral health, particularly among cancer patients, pregnant women, and underserved communities. His innovative approaches, including the use of sound and music therapy to ease dental anxiety, reflect his unique combination of medical expertise and yogic wisdom.

In 2022, he was recognized among the World’s Top 100 Doctors by the Global Summit Institute for his contributions to preventive oral healthcare. He currently serves as the International Ambassador and Continental President of the Dental AI Association (DAIA), leading efforts to incorporate AI technology into modern dentistry.

Looking beyond Earth, Dr. Ranjan is deeply committed to pioneering Space dentistry — a field critical to the future of long-duration space missions and human colonization of other planets such as Mars. Inspired by the challenges astronauts face today, such as the need to swallow toothpaste in microgravity, he envisions inventing next-generation oral care devices and instruments designed for zero-gravity environments. His goal is to make dental hygiene in space simplified, safe, and even enjoyable, ensuring that future space travellers and colonies maintain optimal oral health without discomfort or risk.

Beyond clinics and conferences, Dr. Ranjan shares his mission of health and holistic wellness through his podcast, “Dr. Ranjan Speaks”, and his upcoming children’s book aimed at overcoming dental phobia. His life’s work is centered on a profound belief: to heal smiles, inspire minds, and pioneer health innovation — from Earth to outer space.
